The headlines sometimes say things like this: "Islam rejects the killing of innocent people." That headline is a quote by the Imam Feisal Abdul Rauf.
Those of us who have studied Islamic doctrine know that nowhere in the Koran or Hadith does it imply non-Muslims are innocent. In fact, it implies just the opposite. Read more about that here.
Or, as Anjem Choudary, the London-based Islamic activist, put it: "When we say innocent people, we mean Muslims. As far as normal citizens, they have not accepted Islam, and as far as we're concerned that is a crime against God."
That is pure, unadulterated Islam.
